Short answer: A Tirthankar described as Vitraag (detached) does not experience worldly happiness or suffering in the way ordinary beings do. Their inner state is one of pure, liberated consciousness, beyond the dualities of pleasure and pain.

What Vitraag means here

• Vitraag means free from raga (attachment) and dwesha (aversion). A Tirthankar has shed all karmic bonds and lives in equanimity and vajrā jñāna (kevala jñāna) or siddha state after moksha.
• In this liberated state, they are perfectly blissful, but this bliss is not the same as ordinary “feeling happy” or “suffering.” It is anithik (beyond ordinary feelings) and eternal.
• They are not moved by external events that cause happiness or pain in others. They may compassionately guide beings toward liberation, but their own state remains steady and undisturbed.

How this relates to people

• People may be happy or suffer due to karma, senses, and passions. Tirthankaras, being vitraag, are beyond those causes and effects.
• Their actions (upaya, artha) aim at the welfare of all beings, but they do not act from personal fluctuating happiness or suffering. Their purpose is spiritual upliftment, not personal mood.

In brief

• VitraagTirthankaras: detached, liberated, and in ananda (bliss) that is transcendental and not subject to ordinary pleasures or pains.
• Their state is the same in the sense that it is unwavering and not dependent on external circumstances; they are not alternately happy or miserable as ordinary souls are.

Note on tradition

• Both Digambar and Shwetambar traditions affirm the core idea of detachment and liberation for Tirthankaras. The exact phrasing or emphasis may vary in texts, but the essential meaning remains consistent: they are free from attachment and suffering, established in complete spiritual bliss.
